BRAKE-GEAR MOUNTING.

Application filed April 10, 1926. VSerial No 101,157.

My invention relates to a brake gear lions ing and method of mounting the same to the underframe members of a car and more particularlyfor use in connection with a gondola type especially intended as a coal or ore car and provided with sliding bottom doors, whereby'the load is dumped from the car toward opposite sides of vthe track.

The invention has for its object the pro-V vision of gear housing so Constructed as to permit attachment to one side or member of the center sill of the car nnderframe and also to one of the slide rails of the car bottom sections or doors; the invention, as previously stated, being especially intended Afor use on cars of the type referred to wherein theV brake-staff is mounted at the end of car body and extends through an extension lor `platform on the'car underframe and Lthe car underframe members and showing the gear housing mounted inl place. n

Figure 2 is a side elevation, with certain portions of the bottom door slide-rail in section. .y y

Figure 3 is a perspectiveb view of the bottom casting or member of the gear housing. Figure l is a perspectiveview of the top casting or member looking at the bottom thereof.

Figure 5 is anend elevation illustrating the housing attachedto one memberV of theV center sill and a portion of a slider-ail ad-V jacent to the end of the car.

Figure 6 is avvertical cross sectional view ofthe gear housing.

/My invention, as illustrated in the drawings, contemplatesa two piece housing com posed of the top member or casting 15, see Figure 4;, and the bottom member or cast` ing 16, see Figure 3. Y

The top member or casting 15, atleast in so far as the main body portion thereof is concerned, is preferably more or less of triangular formation, with the three angles or junctures of the respective longitudinal sides or margins terminating in downward-ly disposed legs 17, 18 and19, see 'Figure 4L. 'llhe-legs 17, 18 and 19 are shown flanged along their vertical edgesY as shown at 20; the fianges 2O being preferably7 also con tinned throughout the marginal edges of the main body portion of the casting or member 15, thereby not only reenforcing the entire casting or member 15, but the flanges 20 on the various legs also provide means for reenforcing the connections between the top casting or member 15 and the bottom member or casting 16. The bottom member 16 is provided with upstanding portions or ends 21,23 and 22, adapted yto lap the inner sides `of the legs 17, 18 and .19r

and be riveted orotherwise secured thereto. The legs of both castings or members are shown provided with apertures `for `the reception of rivets or other fastening means.

The topmember orcasting 15 lis shown i provided with suitable openings/24 and 25; the former being intended to receive the lower end Vof the brake-staff 26; while the opening 25 is intended to receive the trunnion or hubof the drivengear. Y The top plateor member 15 on one of th edges thereof, namely on the side intermediate of the legs 17 and 18, is provided with an extension or plate 27 of more .or less width and length; the plate 27 being horizontally disposed and arranged ina plane slightly above the plane of the top member or casting 15, with which it is formed integral `by means of suitable upwardly and outwardly extending reenforcing angesor webs y28 arranged along `the ends and at spaced intervals beneaththe bottom of the plate as shown in Figure 1. The vplate 27 is shown 'aperturedat29in order to permitv it to be fastened or rivetedto the lower flange `or bottom of the centersill member l 30, as shown at 81, therebysecuring the top plate 4inproper place, see .Figure 5. With the `plate or extension27-` disposed toward onek side ofthe mainfportion-of .the top member or casting 15, the .gear housing will .be kdisposed toward one side of the center-sill and `provide proper'clearance for operation of the bralre-staff and `other elements ofthe gear mechanism. n v

The top member or casting 15 on the marginal side intermediate of the legs 17 and- 19 is provided with a lobe or extension 32, seeFigure 1, which is adapted to be dis- Cil posed beneath the laterally disposed flange of the bottom slide-rail 33 of thecar frame; that is to say, the lobe or extension 32 intended to be secured to one ofthe door slide-rails at the end of the car bottom 54 the lobe or extension being shown riveted at Se to the end rail, see Figures 1, 2 and `5.

The bottom 16 consists of a tripartite casting or ramiform plate having the three ramifications or arms 35, 36 and 37. `The arm orportion is shown provided with a countersunk aperture 38 intended to be aligned with the opening2l in the ytop member 15 for reception of the brake-steif 26 and hub of the drive gear. The Vopening' 38 in the bottom member is countersunk as mention'ed to provide a scatti@ for the trunnion or hub t() of the drive gear Li1 of the brake mechanism, see Figures 2 and 6. The hub or trunnion of the drive gear 41, which extends to opposite sides thereof, has the upper end disposed in the opening 24 in the top member 15, while the lower end of the hub is preferably flanged inwardly' at 42 to provide a seat for the lower end of the brake-steif 26, whose immediate end i8 is reducedfor passage through the reduced opening in the lower end of thev trunnion or vhub of the drive gear and through the opening in the bottom member 16.- rlhe bottom member 16 l is alsoprovidedwithan opening t for reception of the extended hub portion 45 ofthe driven gear 4G. lThe upper side of the gear L16 is provided with a small hub or trunnion which extendsinto the opening 25 of the top member 15. The extendedlower hub portion 45 of the driven gear 46, ythroughout most of its length, may be squared to provide driving relation with the spool or chain'drum 47 in order that the latter will be caused to rotate with the kdriven gear 41:6; the spoolor drum, which seats on the lower member 16will maintain the driven elements in proper position.

As will be more clearly seen in Figures 2 and 6, the arm or portion 35 of the lower member 1G preferably extends into a horizontal plane above that of the other part of the member so as toY maintain the drive geartl in proper position and'thus obviate the necessity for employing spacing elements. The bottom member 16" is preferably provided with a vertically disposed reenforcing rib or web 48 arranged to extend throughout the length of the arms of the lower member 16; reenforcing webs or ribs being preferably arranged along member to give it strength and rigidity.

The chain of the brake-operatingl mechanism, which is suitably anchored or secured to the spool or drum 47, passes through the g the marginal edges of they open side of the housing intermediate of the arms or portions 36 and '37 of the lower member and therefore intermediate of the legs 18 and 19 of the yupper member, so ,that the pull or strain will be parallel with the point of attachment'l to the bottom slide rail, whilethe wide bearing and attachment by means of pl te 2? to the center. sill. will prof vide a very rigid vmounting capable of withstanding t-he strains to which it normally is subjected. y f The'invention has been disclosed in what is believed to be the ,simplest embodiment thereof and has been described in terms em- 7 ployd merely terms of description and not as terms of limitation as 'modifications are possible without, howe ver, v. departing from the sp'rit of my invention. i

Vhat I claim is f n 1. In a brake gear mounting, the combination of avcenter sill member, and a bottom door slide-rail, with a gear housing composed of a three-sided ltop plate having depending legs at the junctures ofthe marginaledges, an integralcenter sill engaging portion dis-y posed laterally from a ymarginal edge of the top plate and arranged in a' horizontal plane thereabove, an extension disposed laterally from anothermarginal edgepof thetop plate for kattachment to said slide-rail, and al Y' shaped bottom plate'for supporting the' gear elements, they ends of the arms of the bottom plate'extending upwardly and secured to the e depending legs of the ltop plate, one arm of the bottom plate having the driving portion of thegearing journaled-'thereon while the driven portion ofthe gearing is journaled at the juncture of two arms of the bottom" plate.
